Foxboro RH926SP P0917XV Termination Assembly

Description

Product Introduction & Engineering Value

This is an important Foxboro cross-reference: RH926SP is the current termination-assembly designation that supersedes P0917XV. Schneider Electric’s Foxboro documentation identifies the assembly as an 8-channel, 4–20 mA output termination assembly for the FBM215, with HART capability.

The same RH926SP designation is documented for the Compact FBM218. The termination assembly uses compression terminals and a polyamide construction, while a removable termination cable connects the DIN-rail TA to the FBM baseplate.

Technical Specifications

The manufacturer specifies the TA as electrically passive and identifies RH926SP as the successor to P0917XV.

The certification documentation identifies RH926SP among the termination assemblies for the FBM215’s 8-channel, 4–20 mA HART output configuration, with certification Types 1 and 2.

Critical identification point

= successor to P0917XV.

That is much more useful for procurement than treating the two numbers as unrelated products. The manufacturer’s documentation directly establishes this supersession.

Field Application & the “Trench” Experience

A typical legacy I/A Series cabinet has an FBM215 controlling eight 4–20 mA output loops. The FBM itself continues to communicate correctly, but one or more field outputs become intermittent. The maintenance team initially suspects the module.

The smarter first step is to inspect the complete output path: FBM → termination cable → TA → field wiring → final control element.

P0917XV is particularly relevant when maintaining older installations because it has been superseded by . Schneider Electric’s current documentation explicitly identifies as replacing P0917XV, allowing maintenance teams to source the newer designation without losing the original system reference.

Niche application scenarios

• Control-valve positioning: eight-channel 4–20 mA output interfaces with HART-enabled field positioners.
• Variable-speed equipment commands: analog speed/reference outputs to compatible drives or controllers.
• Process-control final elements: analog output loops where HART communication is required in addition to the 4–20 mA signal.

Transparency SOP: QA & Testing

For New Surplus or Refurbished / stock, the inspection should focus on the termination path rather than simply checking the enclosure.

1. Identity verification — Confirm whether the physical unit is marked or the superseded .
2. Configuration check — Verify that the unit is the compression-terminal version intended for the applicable FBM215/218 configuration.
3. Mechanical inspection — Examine DIN-rail mounting points, terminal blocks, connectors, and cable interface.
4. Terminal inspection — Check for damaged, loose, oxidized, or heat-affected compression terminals.
5. Continuity testing — Verify representative signal paths through the passive termination assembly.
6. System-level testing — Where an FBM215/218 test setup is available, verify representative 4–20 mA output paths.
7. Documentation — Record the exact part number, condition, test scope, and warranty.

Because the TA is electrically passive, a complete functional evaluation should include the associated FBM and termination cable when possible rather than relying only on a bench continuity check.

The Veteran’s Tech Trap Guide

⚠️ Trap #1 — Treating and as unrelated part numbers

They are not. Manufacturer documentation states that supersedes .

PRO TIP: When searching legacy inventory, use both numbers:

That improves the chance of finding usable replacement stock.

⚠️ Trap #2 — Confusing the TA with the FBM

/ is the termination assembly, not the or FBM218 electronic module.

The TA is passive. The FBM handles the active I/O functionality.

⚠️ Trap #3 — Forgetting the termination cable

The TA connects to the FBM through a removable termination cable. The cable is therefore another potential fault point when troubleshooting intermittent output channels. Manufacturer documentation specifies multiple cable lengths and materials.

⚠️ Trap #4 — Assuming all 4–20 mA termination assemblies are equivalent

The / configuration is specifically documented for the 8-channel 4–20 mA HART output configuration associated with /218. Do not substitute another TA merely because it also carries 4–20 mA signals.

Dynamic FAQ

What is Foxboro ?

is a Foxboro 8-channel analog output termination assembly for and Compact FBM218 configurations. It supports 4–20 mA outputs with HART capability and uses compression terminals.

Is the replacement for ?

Yes. Schneider Electric’s Foxboro documentation explicitly states that .

What is used for?

is the legacy termination-assembly designation for the /218 8-channel 4–20 mA HART output configuration. The newer designation is .

How many output channels does support?

The documented configuration provides 8 output channels, each supporting a 4–20 mA analog output, with HART signal superimposed where applicable.

Does include the or FBM218?

No. is the termination assembly. The FBM is a separate component connected to the TA through a termination cable.

What should I request when buying New Surplus /?

Request a photograph of the actual part label, confirmation that it is the / /218 compression termination assembly, condition classification, test details, and written warranty. Current manufacturer documentation is particularly useful here because it establishes the -to- supersession.

Can still be used in an existing system?

The manufacturer documentation identifies as the successor to . For an existing installation, confirm the exact FBM configuration and applicable site documentation before replacing the legacy assembly.
